Abstract

Computer network security has become crucial in managing and protecting sensitive data transmitted through networks. Effective implementation of security measures on every device connected to the network is a critical aspect. This article discusses the use of Standard Access Control List (ACL) as a solution to enhance computer network security, both in Local Area Networks (LANs) and Wireless Local Area Networks (WLANs). This method serves as an access rights provider in computer networks by denying access from unrecognized devices to prevent security vulnerabilities. The results of simulations indicate that using Standard Access Control List successfully blocks computer lab client access to the server, thereby reducing the potential for cyber attacks and improving computer network security.

Abstract

Abstract Solar power plant is one of the developments in the use of renewable energy that has received government support through Ministerial Regulation No.49 of 2018 and Ministerial Regulation No.26 of 2021 regarding rooftop solar power plant. Based on the 2019 solar power plant roadmap draft, the investment cost of rooftop solar power plant per kWp is around 14-25 million rupiah, the amount of this investment is an important consideration for the community to install rooftop solar power plant. One alternative to reduce the investment cost of rooftop solar power plant is to reduce the capacity of the inverter by using lighting from DC lamps. This research was conducted by comparing the efficiency values and investment costs, and using the benefit-cost analysis method to compare a series of relevant costs and benefits between the use of DC lamps and AC lamps for household lighting using PLTS. The results of this research is that DC lamps have a light current of 280 – 350 lumens, an illumination intensity of 48 lux, and a PLTS system efficiency of 98,5% which is higher in value compared to AC lamps which have a light current of 250 lumens, an illumination intensity of 21 lux, and a PLTS system efficiency of 49,3% with the same lamp power of 3W. Analysis of the investment feasibility of on-grid and off-grid PLTS, both 2200VA and 900VA shows that the NPV is negative and the BCR value is less than 1, so the investment is not yet feasible. Keywords: Investment feasibility analysis, DC Lamps, AC Lamps, Solar Rooftop

Abstract

TCP/SYN Flood Attack is a type of Denial of Service (DoS) attack. The TCP/SYN Flood Attack paralyzes the Web Server computer by flooding it with large amounts of data packets so that the communication network system becomes paralyzed. The TCP/SYN Flood Attack takes advantage of the weakness of the data transfer method between the Web Server computer and the client computer. To recognize how a TCP/SYN Flood Attack occurs on a Web Server computer, in this research, a simulation of a TCP/SYN Flood Attack attack was carried out on a Web Server computer from three client computers in a Local Area Network (LAN) network. Furthermore, every hour, the number of packets received by the Web Server computer and the performance of the Web Server computer before and after handling are observed. With this research, it is hoped that it will be known how the performance of telecommunication networks, in this case, Web Server computers, can handle TCP/SYN Flood Attacks both before and after firewall filters are applied.

Abstract

Menyala matinya setiap pendingin yang berada pada sebuah ruangan dikontrol oleh sebuah Mikrokontroler berdasarkan tercapainya temperatur yang telah diatur pada ruangan tersebut, sehingga tidak semua pendingin hidup bila temperatur yang diinginkan telah tercapai. Mikrokontroler akan mengatur pendingin mana yang hidup dan mati pada saat tertentu bila temperatur yang diinginkan telah tercapai. Seluruh pendingin akan mati bila tidak ada orang pada ruangan tersebut, hal ini terjadi berdasarkan tidak adanya pergerakan di dalam ruangan tersebut dalam kurun waktu tertentu. Pusat pengendali mikrokontroler menerima masukan dari sensor gerak dan sensor suhu ruangan yang ditampilkan pada layar LCD. Berdasarkan ke dua masukan ini, mikrokontroler mengatur nyala matinya setiap pendingin udara pada ruangan tersebut, sehingga energi listrik yang digunakan dapat di hemat.

Abstract

Solar energy for public street lighting exemplifies the implementation of renewable energy on a city-wide scale, addressing environmental goals and enhancing energy efficiency. Solar panels capture sunlight, storing it in batteries to illuminate streets at night. Panel efficiency is influenced by sunlight intensity, directly impacting power production. Coupled with batteries, these systems undergo managed charging and discharging cycles for durability. Maintaining battery voltage within limits is crucial—preventing overcharging safeguards against degradation, while careful discharging avoids falling below specified levels. A solar charge controller module is essential for regulating these processes. Monitoring involves an INA219 sensor-based device communicating with the ESP32 microcontroller. The ESP32 transmits readings to a MySQL database server. During charging or sunlight exposure, the system reports solar panel and battery data. Conversely, at sunset, it relays battery discharge voltage. MySQL-stored data is displayed on a web page for real-time monitoring, with graphical representations and tables, automating and modernizing monitoring practices. System testing reveals minimal differences in INA219 sensor values compared to a Fluke multimeter. Accurate data transmission occurs every 5 minutes, and lamp status is trackable via lamp current. This integrated system highlights solar energy's viability for public infrastructure, fostering sustainability and efficiency in urban settings.
